Most GPU work boils down to a few patterns — map, reduce, scan. Each one has a known way to assign threads. So instead of writing a kernel with thread_id:

Most GPU work boils down to a few patterns — map, reduce, scan. Each one has a known way to assign threads. So instead of writing a kernel with thread_id: let c = gpu_add(a, b) let total = gpu_sum(c) The thread indexing is still there — just handled by the runtime, like how Python hides pointer math.
